Results

Anti-CarP antibodies were detected in 117 patients with RA (37.9%), ACPA in 190 patients (61.4%) and RF in 202 patients (65.3%). Two (2.04%) of the NHS were positive for anti-CarP, one NHS (1.02%) was positive for ACPA and three NHS were positive for RF (3.06%). Among disease controls, anti-CarP antibodies were detected in 33 patients (16.5%), ACPA in 29 patients (14.5%) and RF in 64 patients (32%). In particular, 16.8% of patients with systemic lupus erythematosus and 31.1% of patients with Sjögren syndrome were positive for anti-CarP. The sensitivity of anti-CarP, ACPA and RF was 46.8, 61.8 and 64.4%, respectively and specificity was 91.95, 89.93 and 76.51%, respectively.

Erratum

Unfortunately, after publication of this article [1], it was noticed that the percentage of patients listed as RA positive was incorrect in two locations. In the ‘Results’ section of the abstract and in row 1, column 2 of Table 2, the percentage was listed as 34.4%. The actual percentage should be 37.9%. The corrected ‘Results’ section of the abstract can be seen above and the corrected Table 2 can be seen below.
